Does anyone of any natural remedies to recover from flu and cough?

When I or any of my family member get flu or cough, first thing we do is consume a lot of fluids! I still remember, my mom used to give me onion juice and honey for sore throat. I mostly add spicey ginger and lemon to tea because it is good for flu. However, the most important part is, give your body proper rest when you are sick! It will help you get better quickly.
